* Track two sets of back-face stencil stateIan Romanick2009-01-231-2/+4
| | | | | | | | | | | | Track separate back-face stencil state for OpenGL 2.0 / GL_ATI_separate_stencil and GL_EXT_stencil_two_side. This allows all three to be enabled in a driver. One set of state is set via the 2.0 or ATI functions and is used when STENCIL_TEST_TWO_SIDE_EXT is disabled. The other is set by StencilFunc and StencilOp when the active stencil face is set to BACK. The GL_EXT_stencil_two_side spec has more details. http://opengl.org/registry/specs/EXT/stencil_two_side.txt
* swrast: fix redundant texture application in affine_textured_triangle().Brian Paul2009-01-211-1/+9
| | | | | This function does simple texture mapping so disable normal texture mapping before we call _swrast_write_rgba_span() so that we don't do it twice.

* mesa: Remove _Active and _UseTexEnvProgram flags from fragment programs.Eric Anholt2009-01-071-1/+1
| | | | | | | | There was a note in state.c about _Active deserving to die, and there were potential issues with it due to i965 forgetting to set _UseTexEnvProgram. Removing both simplifies things. Reviewed-by: Brian Paul <[email protected]>

* Unify ARB_depth_texture and SGIX_depth_textureIan Romanick2008-10-011-3/+3
| | | | | | | The ARB extension is a superset of the older SGIX extension. Any hardware that can support the SGIX version can also support the ARB version. In Mesa, any driver that supports one also supports the other. This unification just simplifies some bits of code.

| | | | | This is another step toward removing a whole bunch of -I flags from the cc commands. Still need to address driver code...

* mesa: fix issues around multisample enableRoland Scheidegger2008-07-021-1/+1
| | | | | multisample enable is enabled by default, however gl mandates multisample rendering rules only apply if there's also a multisampled buffer.
* mesa: tweak mipmap level selection for cube mapsBrian Paul2008-06-191-1/+15
| | | | | | | This is just a hack. After we convert the 3D texcoord into a face plus 2D texcoord we need to recompute the partial derivatives and mipmap LOD. But we don't have the info to do that. Adjusting the original mipmap level by -1 seems to give somewhat better results than before though.
* mesa: allocate pixel zoom arrays on heap, not stackBrian Paul2008-06-163-10/+20
| | | | Fixes stack overflow on Windows.
* Updated GLSL uniform/sampler handling from gallium-0.1 branchBrian Paul2008-05-142-6/+9
| | | | | | | | | | Previously, the shader linker combined the uniforms used by the vertex and fragment shaders into a combined set of uniforms. This made the implementation of glUniform*() simple, but was rather inefficient otherwise. Now each shader gets its own set of uniforms (no more modelview matrix showing up in the fragment shader uniforms, for example). cherry-picked by hand from gallium-0.1 branch

| | | | | Set _ColorDrawBuffers[0] = NULL if no renderbuffers enabled. Check that _ColorDrawBuffers[0] is non-null before dereferencing in a few places.
* Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.Brian2008-01-0610-148/+104
| | | | | | | | | | | These fields are no longer indexed by shader output. Now, we just have a simple array of renderbuffer pointers. If the shader writes to gl_FragData[i], send those colors to the N _ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or the fixed-function color) to the N _ColorDrawBuffers. A few more changes and simplifications can follow from this...
